Descaling the washing machine

At Bosch, we are well aware of the negative effects of limescale on washing machines, especially in hard water areas, and the worst of these effects is a build up of limescale on the heating element, which can result in this component being less effective at heating up the water, or even the need for this component to be replaced by an engineer.

It's for this reason that we highly recommend descaling a washing machine every three to six months with our tested and approved washing machine descaler to protect against the build up of limescale deposits and to prolong the life of your appliance. Watch the video below to learn how to descale a washing machine the correct way.

Step by step guide

Ensure the washing machine is empty and all the laundry is removed.

Open the detergent drawer and pour the entire contents of the box into the left hand compartment.

Close the detergent drawer, select a 60°C programme without pre-wash and start the appliance. Let the programme run until the end.

Run the programme again at 60°C, this time without the descaling powder, to thoroughly clean through the appliance and remove any residues. Again let the programme run until completion.
